This question was inspired by my hatred of Temporal Anti-Aliasing which, in many games nowadays, is poorly used as a performance bandaid. On lower resolutions it will smudge and blur the image and certain bad cases of TAA will cause visible ghosting.
Yet in spite of all this, certain games won’t let you turn it off or have hair/fur/foliage look like dogshit without it so sometimes I still use it.
Google Workspace. I have several clients who insist on using it for unknown reasons. It creates unprofessional looking work products. And in some cases, it is just plain kludgy (slicers randomly shoot themselves over the Sheet, page numbers randomly renumber when the footer is updated, etc). The part that gets me the most is that it is similar in price to other productivity suites, but often our clients opt to buy Zoom and Slack on top of that - basically doubling the price.
I’m forced to use Google Workspace and I absolutely hate it. The document suite is so horrible when trying to do anything that isn’t a basic document or spreadsheet. Gmail sucks for long email threads and anything with attachments and the search is useless. Google Chat is a barebones piece of shit compared to Slack.
Luckily I’ve been able to get Microsoft Office for the things that require it, including Outlook using the GWSMO tool.
