Shouldn't a company of that size and revenue be able to do both at the same time?

I have absolutely no evidence to back this but I think they are actually making money of the bad tooling.

Firstly, because it requires and also creates an army of cloud AWS consultants that works as free sales persons for AWS.

Secondly, this army creates overly complicated and expensive solutions which then only they can change, and they never do because it looks good on CV.

Maybe a bit too cynical.
