Most tech sucks because it's closed source. Closed source products are typically made with "the least amount of work done to sell for the most amount of buck". So standards are only sloppily and partially implemented (or sometimes purposefully badly or differently to ensure incompatibility), and bugs after sale won't be fixed because why would they? They already have your money. Middle managers will work hard to ensure more money goes to advertising and marketing than to actual development.

Then there is the embrace, expand, extinguish mentality (hello Microsoft!) to force customers to stay around their shitty products. Microsoft 365 and teams shit are perfect examples. The company I work at currently uses it and it's beyond garbage shit that is expensive as hell. Not an hour goes by without me being confronted by bad design, bugs, bugs, bugs, so many bugs... And it's all designed to ensure you stay in their little walled garden. I can't change this today, but I'm planning to be rid of it in about a year from now, fingers crossed.

In my experience, open source software is fucking awesome because people built it to actually build something awesome. Standards are implemented to the letter, bugs are fixed, and it all works and looks awesome.
