Seeing that the OP is low rated and the number of posts in the thread in the hours and first days after creation, I didn't care to poke my nose in here, expecting the usual apologists of "new" no-values, just-growth-and-profit, "we-want-to-be-another-Steam-and-target-their-audience" GOG to bring out the big guns. But after mrkgnao mentioned it in another thread, had another look and saw the list in the OP, which I must say is rather impressive.
Now, after being the one
calling for a boycott after the "good news", and then being fooled by their "back to our roots" PR stunt that only lasted about half a year, till they really opened the floodgates, I obviously fully support such initiatives. Not because there's any hope of improvement, GOG have only been getting worse basically since they became GOG instead of Good Old Games, those who called it then being the ones who really saw things properly, while many of the rest of us needed the nearly 2 more years until the "good news" to really realize what was going on, and some maybe didn't even then. But because it at least sends a message and shows that there is a reaction, and at least a specific lack of support, for what's going on.
So, yes, also joining the boycott for the duration of 2021, in the sense that I won't make purchases on here. My conditions would be fewer than the OPs, basically either fixing or, if that doesn't happen, removing any games that have any sort of DRM, anything that may at any point require a connection or activation, for single player (so Gwent is infuriating, but not a dealbreaker in itself, being multiplayer only), and ensuring that those who won't touch Galaxy don't get worse treatment compared to those who do, so offline installers not falling behind or missing features compared to Galaxy ones, people wanting offline older or different versions that are available through Galaxy receiving them, and no freebies or other similar benefits only for Galaxy users. The other demands in the OP are laudable but for me getting rid of regional pricing, at least in the sense of regions paying more than the US price, is far above any of them for me, and so far I shamefully haven't even returned to my own call for boycott from back then because it's not happening, merely making sure to restrict my few purchases to the ever dwindling number of games that don't have such pricing, so...
Fully support the original call, however, and those who join it for all the listed reasons, of course.
