Been there. I was your-services-are-no-longer-required at a job in 2013; that's what precipitated my career pivot into devops/platform infrastructure. I was out of work for about eight weeks, five of which were by choice (and my new company paid me a significant bonus to start that early).

That said, yes, the notion of "hey, I could get fired for this" did sometimes enter my head afterwards, but I never feared it, because I knew I had options.
