Those of us who came up in the 80s and 90s remember that bad behavior and even worse software is baked into Microsoft's DNA.

Had they had the opportunity, they would 100% have taken it. Windows was never about serving a good experience to customers, it was always about serving the Microsoft-owned experience to customers—and these two things are very much mutually exclusive.
But it doesn't matter where it originated or who first said it. The reason this phrase gained so much popularity is that outside observers could see that's their strategy was (and still is).
