Because those services solve the problem for them. It is the same thing with GitHub.
However, as predicted half a decade ago with GitHub becoming unreliable [0] and as price increases begin to happen, you can see that self-hosting begins to make more sense and you have complete control of the infrastructure and it has never been more easier to self host and bring control over costs.

What you have just seen with coding agents is going to have the same effect on "developers" that will have a decline in skills the moment they become over-reliant on coding agents and won't be able to write a single line of code at all to fix a problem they don't fully understand.
