A few individuals doing that is meaningless. Individual action only matters if you can get a critical mass of people on board.
It also ignores the reality of the prisoners dilemma, in that a service can be bad for society over all but within that society it is better to use it than to not. Everyone driving around huge cars is a clear example of this. When a scenario like this is identified the correct thing to do is regulate it with law.
Why do you want to be not "meaningless"? If they don't like something that they don't have to use, they are free to do that. How is breaking up big tech going to solve anything.
Also big companies are easiest to regulate and all the countries regulate them all the time. If you have 100 different TikToks, they threaten democracy even more as the profit incentive push towards extremism in any case.

The same should be true of democracy, but unfortunately, in representative democracy, you only need to convince a few representatives, which does not actually require a critical mass of people agreeing.
Why not do both, change your own patterns and change the regulatory frameworks to make capitalism benefit society? Though I would go as far as saying: use regulatory frameworks to save capitalism. A market where a small set of winners takes all is not functioning capitalism anymore.
