The 6502 was a very robust device manufactured in NMOS technology.
The original target market was motorolas very lucrative military/space
6800 market, so the chip had to match or exceed the 6800 on all points,
including accidental damage.
The first version, the 6501 was in fact pin- but not instruction-compatible
with 6800, but Motorola had a legal fit and MOS gave up on that idea.
The fact that 6502 mainly ended up in Commodore computers was mainly
a matter of its lower price. Later the crash in microprocessor prices
saddled Jack Tramiel with a huge overpriced inventory which made him
outright buy MOS to avoid a repeat performance of that problem.

Never attribute to malice what can adequately be explained by incompetence.
