In 1995 we boycotted Shell for environmental reasons and it worked: https://en.wikipedia.org/wiki/Brent_Spar

Towing of the platform to its final position began on 11 June. By this time, the call for a boycott of Shell products was being heeded across much of continental northern Europe, damaging Shell’s profitability as well as brand image. […]

So it needed more than a week of concerted boycott action to bring big business into trouble, but not unlimited boycott.

Sorry, I have to use German key-words below, as those are strongly bound to the worst part of our culture and history and are not translatable, maybe you get the concept by looking at translated version of my Wikipedia links:

With regards to the timing, only few days before the “Machtergreifung”, in the USA, what Meta does looks to me like Vorauseilender Gehorsam as preparation to use the 2.0 digital versions of Volksempfänger to enable entities with similar job and plans like Joseph Goebbels to mass-share propaganda lies. In Summary: Big tech started with their Gleichschaltung without any order (yet) nor resistence.

As said, this is what the news about “fact check being removed” triggers for me. Not sure if OP meant the same, though.
