paypal’s business model is basically theft. They regularly “freeze” accounts of people that have money to be taken, refuse to unfreeze them, and then when it eventually turns into a class-action lawsuit they settle for pennies on the dollar (that mostly goes to attorneys anyway). When it happened to me over 10 years ago, I was doing remote tech support and getting paid via paypal. Had a business account that was like 10 years of use. Then one day they froze the account and told me there was “suspicious activity”.
When I appealed and asked what suspicious activity they found, they simply said that there was money in the account and there wasn’t before… Then they asked for, specifically, ebay transaction IDs and UPS or Fedex tracking numbers for the products sold on ebay. I explained to them again that I was not selling on ebay and was doing remote tech support. The person on the other end of the phone just said “ok, well, then your appeal is denied. Your account is staying frozen” and hung up.
I ended up just refunding all the transactions that were recent enough I could (because that was the only thing I could do with the account) and sent those customers a note explaining briefly what happened and that I would rather have done the work for free than have done it so paypal can steal the money…
Eventually got tacked onto a class action and got a low double digit payout almost a decade after losing a few thousand…
You can’t plagiarize mechanics because you cannot copyright mechanics… And you don’t want to live in a world where you can. Imagine if the first company to make a first person shooter game copyrighted it… Or if Nintendo owned the rights to all 2d side scrolling games… Gaming would have never grown to what it is today.
Hell, even board games would have been crippled by this kind of copyright.
