It’s only piracy if you grab a cutlass and storm the local shops. It’s time to call it what it is = digital theft / running unlicensed software / whatever. If someone hacks into your accounts, I doubt you’d call them a pirate for stealing all you personal videos and pictures, taking over your steam account, ‘borrowing’ your netflix, and so on. The whole thing is deeply uncool.
Personally I wish the laws would change to make copyright non-transferable from the original artists, who deserve reward for their efforts but shouldn’t be a meal ticket for others. I’d also like to see abandonware legitimised - if folk can’t buy it then it should be fair game.

I guess most developers go for a logo rather than a spinner. Maybe they worry that folk will forget what app they tapped on?
