This sounds great. But if you didn't buy anything in the first place there's also zero effect of boycotting. Then the movement can of course succeed quite easily, but at no net gain.
I feel like you tried to dodge the elephant in the room: the tech. The hardest part to get rid of is the technology, and in particularly the tech stack. Social media, servers, windows, outlook... The dependency is real at all levels, and I've yet to hear of any company trying to escape. This is also where I believe the boycott will fail at an consumer level, people will keep using META, stream from Netflix, order from Amazon etc. Since people are still using these, so will our companies and politicians.
Awesome! ๐
Perhaps it's me who is in a bubble IRL!
Even if the economic impact turns out to be negligible it is clear to me that the movement is born out of a change in mentality, which I'd argue is even more important then the monetary impact.
