I don’t know the finances, but I wouldn’t be surprised if their margins are low enough that their profit comes from advertising and data gathering post sale. So all this bloatware and advertising is subsidizing a high quality product and if you can strip out the unwanted stuff you’re probably getting a good deal at the expense of the company
You're showing the company that shoving advertising and data gathering into products will help them make products that sell.
What you buy is what companies put out into the world.
