If the reply was along the lines of "This is a new firmware check to curb fraud related to undisclosed aftermarket RAM upgrades with potentially unreliable chips." - I'd be fine with it, but basically just coming out to gaslight the user about the issue leaves a very sour taste in my mouth. In the end, they had to come clean anyway, big surprise.
I say this as someone who has been loving Pis despite their price for the straightforward and reliable long-term software support. Not gonna pretent like I'll never buy a Pi again, but it's another strike moving me to explore other options in the future.
