Am i glad to live in the EU with the right to repair

Seems easy to circumvent unless an EU-country decides to be hard-assed in their implementation, though. If the repair cost is >50% of the new price, how many consumers are actually going to opt for repairing rather than getting a new device, especially for device classes like smartphones that require active effort from the manufacturer to keep the software in a usable state?

"Ending is better than mending"

Freeing the software solves the second point.

Is it because if fixing it were cheaper than replacing it, the company that sells it would make less money?

part of it is wealth disparity. So much money is circle jerk circulating at the top that most people can't afford to hire themselves.

Is that currently part of EU's right to repair?

Idk. I am just saying that if the specs of the ISA and the interface to the devices are open, free software can take it from there
