I mean, as i stated, i can’t really vouch or argue against pf2e, since i dont play it and haven’t really read the rules of it since it was in playtest. That said, just googling, i see some things that could be considered exploits like a reddit thread talking about being able to do 520 damage in one attack, some chatter about a “resentment witch” being able to make power word stun or color spray effectively permanent, and a youtube video by the rules lawyer about “OP builds”, so it seems like there’s at least some system exploitation going on.
Obviously a tighter controlled system is less vulnerable to exploitation (see D&D 4e), but that also doesn’t mean that is necessarily doesn’t exist. Another counter example system with lots of rules and lots of exploitation of them would be shadowrun, especially older versions, which were even worse than D&D in some respects.
They were ripping off both their users and anyone using affiliate links (including the content creators who promoted them)
During checkout, when you clicked the “find coupon” button in honey (which it prompted you to do on screen during checkout), it would strip out any affiliate link and add their own. So if you clicked on a product from a review, they would strip out the referral link from the YouTube video or website that sent you and indicate they sent you instead and get the commission.
In addition, they were working with online retailers and basically extorting them. They said that if retailers paid them a fee, they got to pick the discount code that was used during checkout. So if there was a 20% coupon and a 5% coupon, stores could pay them to ignore the 20%.
This, in turn, was basically faking out their users, thinking they were giving them the “best deal” like they claimed to.
