TrackerControl scans all installed apps for trackers and blocks most tracking requests. It also lets you block internet access for certain apps and can monitor system apps such as Google Services. Be aware that TrackerControl often blocks trackers that are necessary for an app or certain features to work properly, so you may have to manually disable blocking of specific trackers.

Have you used the app in question? There’s animated hi res backgrounds that have to be loaded for diff locations, a live map, tons of detailed widgets and animations… 300MB seems reasonable to me. You might not want any of these things on a weather app, hence there are many to choose from out there ;)
Jesus they’re even dumber than I thought
