Yeah, this with BT on the Roli what made me move on. Actually. I think there's need to start another thread about all these, keyboards, which you have to pay a deposit on, and later on, it didn't turn out that you expected. We know from this thread that Roli expanded their firmware to exclude something that was possible initially, but took it away (I think it was about the sensitive tune, side to side, with the possibilites to change pitch in even more prickly ways) and wasn't possible to retract it to older firmware.
Like with all computers/phones/electronic gear, where you make warranty elusive and shady, since everything is changed within the firmware updates, and if you do not like the new firmware, i e you just HAVE to buy additional BT stuff (say) in order for it to function, you will not comply to that, but can't leave the keyboard back for warranty purposes. I e if you knew about this, or the keyboard had this in the first place, it would have been a deal breaker for you instead of a maker. Now, after you bought it, a year down the line it is incorporated with features, that would have made you NOT buying it should you detect this in the first place. They create a trap, in which you have to buy the hardware, and you're stuck with it.
I think it's a slippery slope if all or most manufacturers does this. That we're still beta testers to them, and will become beta tester and having to pay for it. I e they release something that's not supposed to be released yet... or... ever. Mobile phones like Librem, Fairphone springs to mind, talking about other areas.
