Reddit, which hosts the r/linux subreddit, is a for-profit company driven by growth and engagement, like other numerous other platforms in the corporate members. I imagine this is precisely the kind of tension that prompted OP to ask the question (but I’d happily let them clarify).
I’m arguing that discussion on r/linux if you are working for one of those corporations and want to discuss technical questions is not incoherent.
If you are though interested in Linux for the moral and ethical aspect then it is in direct conflict with the moral and ethical decisions that such platform took and keep to this day. Consequently using r/linux is a problem in one case, not in the other.
Does it make sense?
When is the last time you carried your desktop outside? Forgot it somewhere?
