You're literally the only one complaining about it, and you've complained to many yet most don't care. It's hard not to make it out to be you having ulterior motives about it compared to you trying to be protective of the reward pool and wanting what's best for hive.
If giving people a few cents for putting in the time to share their or other people's posts is overrewarded, people are free to downvote them. Although it's weird that they'd focus on that compared to the thousands of posts farming autovotes/delegationforvote projects, etc.
You thinking the reward pool should only be used for posts and comments is quite limited thinking. Naturally however if author rewards are being farmed to only benefit a few, then it's not really the same as posh. If posh ends up doing well, you benefit from it indirectly as well through your stake in this ecosystem.
