Google support seems to charge per person, so suppose you are a few persons, ie at least 3 sharing the support then it's $750/month. Also, you are assuming US salaries, when looking at many other countries $250 is upwards 10% of the salary. Google support is valuable, but, going with AWS for example is a lot cheaper. Now, if you are a VC-backed or otherwise funded company, then this is a non-issue, but there are hundreds of thousands of businesses that have a total spend on infra that would be less than the support fee from Google.
