My point was more along the lines of online being impractical. Sure, you can still connect to servers running old software (in which case kernel updates aren’t useful to you anyway), but anything with modern security or software is going to just not run at all on it, whether because the software is too heavy for the processor or because it simply was not compiled for it (and cannot be).

Point is, I think we both agree that the only reasonable usecase for these processors is offline or on a separate network (LAN/tunneled/etc).
