Intel sort of does it, too. Like they have started calling some of their Atom CPU's "Celeron", while they still serve more powerful Haswell Celerons on the market, and the naming is just slightly different (a letter). They don't exactly replace it in the same model, though, so I guess they are not quite that bad yet, but they try to be misleading about it, too.
