No, the business goal is to lie, trick, cheat and steal, to fuck a potential customer over so they part with their money.

That the customer may not be satisfied afterwards doesn't matter - there are plenty of mitigation strategies, such as lock-in effects, playing off sunk cost fallacy, or drowning negative feedback on third-party sites with bought ratings, reviews and social media likes.

Seeing a site like this should light an immediate warning site in your head, telling you that you don't want to be on the business end of their business goals.

I myself am blocking these annoyances with an adblocker so I'm in the same boat as you.

That being said, the value that these patterns are gaining the businesses that employ them, must outweigh the value lost from people who are so annoyed that they take their business elsewhere.

It is how it is, unfortunately.
