We're winning, boyos!!!
Are you really, though?
You are right that GOG is in dire financial straits, so in one sense, yes, the Boycotters could be considered to be "winning" from that perspetive.
But if you fully win, and GOG gets shut down, then your GOG games library becomes much less secure, given that you would never be able to access your games from GOG's servers again in the future.
Even if you have backup(s) of your games, having an extra backup that is perpetually available from GOG's servers would still provide much more security for your GOG library than would having your own backup(s) alone and with no support from GOG's servers.
Therefore, for those reasons, even if the Boycotters win, they still lose.
Having said that, I'm not intending to bash the idea of boycotting GOG, as I can understand the very good reasons for why many former customers do that, and I am supportive of those reasons.
But it's a complicated situation, since GOG going down will be a Loss for the Boycotters as well.
