If you dig a bit deeper the claim is more or less that Ahmed ibn Idris al fasi had wahhabi inclinations in opposing istigatha and bidah. Just check the references and the citations and you might find something interesting.
Interestingly his life coincides with the wahhabi era as well.
https://en.wikipedia.org/wiki/Slimane_of_Morocco
During year 1792 Morrocco is said to have been ruled by a wahhabi leaning sultan as well. Make whatever you wish of it... but Ala Hazrat and the scholars of Ahlus Sunnah have always been staunch sunnis and opposing wahhabis , so that no one could make any claim of them ever having Wahhabi tendencies.
Another interesting thing is the case of Muhammad Hayah al sindhi and the likes of ibrahim al kurani, their teachers and views and how certain movements came about, think of the Kadizadeli during the ottoman era for instance.
This same ibrahim al kurani is said to be the murshid of the jahriyya naqshbandis in China through Ma Mingxin(Mohammed Emin) , who were opposed to the khufiyya. They had violent clashes amongst eachother.

Perhaps Wahhabism was not invented overnight and the teaching of ibn taymiyyah were not fully buried prior to Muhammad ibn Abdulwahhab...
The interesting thing about history is seeing what event and circumstances lead to the present.

Focus more on the references and not so much on the wikipedia article itself. Just gives more of an insight into what the environment was like at the time and where the final domino fell that gave birth to wahabbism and its offshoots. At least from there on you can actually make some sense of the wikipedia articles...
Then there was also the conflict between the Qadiriyya shuyookh in Somalia against the Salihiyya.
See :
https://en.wikipedia.org/wiki/Mowlana_Abd_al-Rahman_Nurow
Said to be a diciple of Ahmed ibn Idris Al fasi..
https://en.wikipedia.org/wiki/Muḥammad_ibn_'Abdallāh_Hassan
Said to be a disciple/student of the former.
Under the 'The Dervish War'
I found this of interest:
Fight against the Qadiriyya
Despite leaving Berbera after being rebuked by the leading Sheikhs of the rival Qadiriyya school the enmity did not end. Heated poems would be exchanged between the Sayyid and prominent Sheikh Uways al-Barawi from Barawa, the leader of the 1908 Benadir revolt.[35]
Uways recited this qasida criticizing the Sayyid:[36]
صل على محمد واله واصرف بهم من كل سوء داهيه
من اقتدى محمدا بشرعه لا يقتدى جماعة الشيطانية
هم المبيحون دماء العلما والمال والحريم هم إباحيه
ويمنعون الدرس للعلوم كالفقه والنحو هم الكراميه
بكل شيخ مات كالجيلاني لا يتوسلون كالجناحيه
لا يقتدرون خلف من له شعر سيماهم التحليق كالوهابيه
ويشترون الجنة بمال في دارنا جهرا هم الكلابيه
ويختلون بالحريم للإجا زة كأمهم فذا سفاحيه
يتبعون رأيهم لا كتبنا ويدعون النور من بلاسيه
ويفعلون النكر في ذكرهم فعلا وقولا يقتضي كفرانيه
كاللعب قائلين أألله شكا به جلهم الشماليه
لهم ضجيج وأنين وحنيــــــــن وفحيح كالكلاب الناحيه
ويكثرون الحلف بالطلاق وينكرون الكلفة الالهيه
ضلوا وأضلوا العباد في الثرى برا وبحرا اي من السماليه
أليس ذو لب وفهم يغترر بهم ففر عنهم كالدواهيه
—Uways Al Barawi Qasida on Salihiyya
Translation:
Give a prayer to Muhammad (Sayyid) and his family and turn, through them, from all evil calamities
The ones who has imitated Muhammad (Prophet Muhammad) through his law does not follow the faction of Satan
They are the justifiers of [spilling] the blood of the ulama and of wealth and women, they are libertines
They prohibit the study of sciences such as law and grammar, they are the repugnant
Through every Shaykh who has died such as Al-Jilani they do not seek petition, like the faction of sin
They do not follow behind the one who has locks of hair, their characteristic is to wear their hair long like the Wahhabiyya
They trade paradise for cash publicly, in our land, they are a sect of dogs
They dally with women who come for license, like with their own mothers, and this is fornication
They follow their own opinions, not our books, and they claim to the light from the faction of Satan
And they practice denial at their dhikr, in word and action it requires blasphemy
Like their game of saying Is it God? - doubting him, the northern faction (dervishes) glorify them
They make a clamour, a wailing and groaning and howling like mournful dogs
And they frequently use the oath By the divorce and reject the ceremony of Allah
They have gone astray and make people go astray on earth by land and sea anyone from [among] the Somalis
Is it not the owner of reason and understanding deceived by them?
Then flee from them as from calamities
Wallahu 'alam, but definetly worth digging into.
