Comments and posts that are just for entertainment, sure. But technical help isn’t a transaction between you and Reddit. It’s a friendly transaction between users purely out of the desire to help, and leaving it available to those who have the same question.
It’s like those posts asking for assistance on something extremely specific you also need help on, only for the next post to read, “never mind I figured it out” with no additional information.
Yeah, you might hurt Reddit by removing that information, but you’re also hurting everyone else that may need help in the future.
It’s both.
