That's an important question to ask. For me (and I want to make very clear that this is exclusively how I handle things for myself) there is a huge difference between things I use (or what I call passive association) and things I work on or contribute to (or what I call active association).
While im ok-ish with using their software if they don't really profit from my usage, I wont be actively helping them. Given the state of the world and western society, I can't really escape using products that are unethical and as a software developer working for a company I can't really decide who gets to use my paid work and since I very much like having a bed and a roof and food and even some comfort in that, I'd rather stick to my job, but I can make a choice on who I support with my free time.
