My parents were talking about this sort of thing a few years ago--a company is only good until it takes over, then goes to shit.
For example, Wal-Mart in the 1990s was better in pretty much every way than Kmart...Kmart was plagued out of stocks, Wal-Mart had it. Kmart had old, crappy stores, Wal-Mart's were more modern. Their products were generally better, and Wal-Mart had McDonald's and Daytona USA.
Then Kmart went bankrupt and their stores disappeared, and almost immediately Wal-Mart's selection and quality dropped off the cliff within a few years.
Same thing with Amazon.
