Yes, maybe. I do know Linux pretty well and don't consider sysadmin costs a big drain on my own company or time. I can see that it'd be much more expensive if you hire people who don't have much UNIX experience.
On the other hand, I've experienced first hand how cloud costs can explode uncontrollably in absurd ways. One company I worked at had a cloud cost crisis and they weren't even serving online services, just shovelling money into Azure for generic dev services like VMs for load tests, DBs for testing, super-slow CI agents, etc. They never managed to properly fix this because of the mentality you express here: a few hundred bucks a month here, a few hundred there, everyone gets access to spin up resources and it's all worth it because we're all soooo valuable. Then one day you realize you're inexplicably burning millions on subscription services and cloud spend, yet nobody can identify quite why or on what, or how to push costs down. Death by a thousand cuts, it was quite the revelation. Free cloud credits are murder, because they embed a culture of profligacy and "my time is too valuable to optimize this". By the time the startup credits run out it's too late.
