I thought I'd reiterate the request to throttle the download speed as a neighbourly/quality of life feature (so other users can continue to watch streamed video on the same network).
It's in the Epic Games launcher, Steam app, Uplay app, Battle.net app, Origin app, Rockstar app and the GOG Galaxy app. If you have Windows 10 Pro or above, you can use gpedit (group policy) to limit the download speed of the Windows Store app too (the Store doesn't have it built-in).
The suggestion was mentioned in these threads:

As download sizes increase this feature will be more useful (e.g. Pyre at 6.9GB, Runner3 1GB etc.).
