In line with remote-bricking discontinued hardware, these policies only serve to generate eWaste.
If you sell programmable hardware, or really anything with embedded software, you should be required to make all the tools and software available to end users (doesn’t have to be free, but shouldn’t require a subscription or support contract either) in perpetuity.
Licenses to enable additional hardware features are fine, but they must be granted for the life of the device (i.e. as long as it can be kept working), not an arbitrary “we think the life of this thing is 5 years”. You should never have to keep paying to use a device you already bought.
You think that's bad? I bought a "RAM upgrade" over the phone from HAAS for a CNC machine back in 2016ish. The upgrade was from 1mb to 16mb of RAM.
The technician on the phone told me to go to the machine and punch in a series of keys followed by a 21 digit code. That was my ~$2,000 RAM upgrade.
The RAM was always there. It was just locked away as "reserve value" for the manufacturer.
In this case, you already bought and paid for the additional RAM. The manufacturer is refusing to let you use it until you pay additional money, even though you theoretically own it already. That’s not providing a service, it’s just extortion.
If you could somehow prove that the additional RAM was not factored into the original cost of what you bought then this might be fair (albeit wasteful) - but I doubt it…
