I often play a game called Sailwind. Very relaxing, but impressively deep sailing sim. It’s been early access for a couple of years, but the (solo-)dev is active, new features are added all the time. If he would release a paid, cosmetic dlc: I’d buy it in a heartbeat. I think it would be nicer than to “get him a coffee” or sub to his patreon.
What I’m trying to say is: not all early access is bad, not all paid dlc is plain greed. And the combo is not necessarily toxic.
This is only useful in the unlikely event that the stolen bike turns up somewhere. Just like engraving, it won’t prevent a single theft. Better to buy an airtag and two decent locks.
