This crosses into personal attack. The site guidelines explicitly ask you not to use HN for cross-examination, and hauling someone's personal details into a different thread is particularly nasty. https://hn.algolia.com/?dateRange=all&page=0&prefix=false&so...
Covid definitely did have an impact on some dev work. I run a consultancy and business development is a lot harder when you can't have face to face meetings with potential clients or prospect for new clients at events.
Some of us try to start small businesses on the side, just for fun. I'm retired, but I do. I assume active devs do the same - buying a restaurant or a bar that suffered due to covid can be quite cheap at the moment.
Now that's been said, going through the person posting history with a fine comb like you did strikes me as rude.
