The battle of the Commodore 1541 vs clones existed because Commodore’s early track record was rather imperfect.
Commodore’s 1541 floppy disk drive was the first consumer disk drive that cost less than $300, so it has an important place in computing history.
What some people forget is that while it broke new ground, its early owners loved to hate it. It was slow, it was loud, and ran hot. Early units were unreliable too. And to add insult to injury, in 1982 and 1983, Commodore couldn’t build them fast enough to keep up with demand. Even though it had problems, people were eager to buy it. (Disk drives for other computers tended to be problematic too, in this young industry.)
The 1541’s problems led to a number of clones that tried to be a little bit better.
