It really was. Apollo
was the reddit UI for me. The old reddit web page looks awful on a phone. The new page is a mess of algorithmic disaster on any device. I cannot stand their 1st-party app. When they killed the API, I no longer enjoyed using reddit on my phone, which is where I accessed it 95% of the time. They made it pretty easy for me to stop using the site at all.
OTOH, I had previously posted often enough to get in on the IPO, and that made up for a lot of the annoyances.
