That's what I thought, too. I've still been getting updates for it and, like you said, just got one very recently. I love that app! I got my mom to use it, and she loves it, too.

Check out yr.no, it is made by the Norwegian Meteorological Institute. I think it is pretty good internationally too

Quick Weather - for the radar and day overview.

Forecastie - for the humidity, rainfall, wind, and temp weekly graphs.

Both are in f-droid repos.

I haven't yet found a nicer one than Overdrop. I'm not a big weather geek, so I don't need all the minute details. I think Overdrop is a perfect mix between lots of relevant data and gorgeous, simple design. Paid for pro, haven't regretted it. I have (currently) installed and tried like 10-15 different weather apps. OD is still the only one on my main app page.

I think they're wrong. I use it through F-droid and still get updates. The most recent was within the past couple weeks.
