As an avid apple disliker, they really got a lot of things right with 10.x, with snow leopard hitting it out of the park. Everything from them around that era was slick. If I wasn’t a poor college kid running a 5 year old eBay Thinkpad I would have been sucked into their oppressive ecosystem in a heartbeat.
I’m my experience “I could sue, but won’t” is only ever used as a threat by narcissist assholes who got called out and don’t have enough evidence to sue, because if they truly did, they would. His ego was hurt by his own shitty attitude, so he’s using threats he can’t back up to be a bully. He’s basically saying “I have more money than you and can drain your resources with a frivolous lawsuit if I wanted to”
