Why would they do anything else?

They own a huge chunk of the internet now - with many, many companies having deeply integrated CF into their own stuff.

Switching costs are so high, from a business standpoint, investing in technical excellence would be wasted money. They're just a corp like everyone else. Gravity also applies to them.

Don't take this as "they're right to do so". Take this as "You should never have started integrating their products this deeply. This was inevitable and obvious."

Using CF always was trading short-term wins for long-term losses. We're now entering said long-term.
