Selling something with a markup is how business works. It's up to consumer to decide whether the added value is worth the markup. Seems like it's not for you.
As I mentioned elsewhere in this thread already, while the Librem 5 is becoming dated, there's still no upgrade path on the market. You need to switch to a completely different category of devices in order to get something more performant than that. I hope that'll change soon, regardless of whether it will be Purism coming up with L5v2 or someone else with their own thing.
