That doesn’t actually do anything…

Opting out of buying from a service only hurts them when the service is anti consumer.

When the service is large due to pro consumer reasons then not buying just hurts yourself.

An anti consumer service relies on momentum to maintain it self. Hoping people are too lazy to leave. Since growing the customer base is near impossible with out dirty tactics.

A pro consumer service grows regardless, since it’s the best option. It doesn’t have to do dirty things to grow a customer base since by default the other options are worse.

If you just stop buying games entirely then you also do not matter you removed yourself entire from the equation.

You would need to start buying games from non valve sources that are in direct competition with valve. So things like the Amazon store, Uplay, etc.

Which do the same things and worse.

Functionally you do not get a choice of voting with your wallet. Because it doesn’t apply here.

So all your doing is being stupid at worse and nothing at best for the cause.
