I was just thinking about this! For me it's "All build tools". I rely on them so heavily, and they have started putting nag/beg messages in them and everything.

I was just thinking about this! For me it's "All build tools". I rely on them so heavily, and they have started putting nag/beg messages in them and everything. I know they'd really appreciate the funds but still I've never even thought about doing it. I kind of don't understand why anyone would ever work on a build tool/package manager for a language: I expect them to be bug-free, stay out of my way, be fast - and even if it is all those things - I'll jump ship to the next big thing as soon as it's available without any appreciation for all the work that went into it!
