Sublime Text.
I sat through scores of interviews and pairing sessions with developers back when Sublime was a thing and the vast majority (>90%) of devs would rather exit out of that pop-up asking for support then pay the measly $30 or whatever regardless of their massive incomes and increased productivity that Sublime brought them.
We developers are no more altruistic than anyone else regardless of the lies we fed ourselves in the early days of FOSS, internet, bitcoin, etc.
