Every time when a YouTube video is embedded in Lemmy, a bot appears, suggesting to use Front-end Piped (or another) instead of YT, which is certainly recommended, due to YouTube’s inherent privacy concerns.
However, then it is not understandable, why in the case of images Imgur links are happily allowed, which is infinitely worse in terms of privacy, which shares user and usage data with the worst existing advertising companies, which makes it in little less than spyware.
As a suggestion I present 2 alternatives, which in addition to, as EU products, strictly adhere to the GDPR standard and even more.
As the main FileCoffee service, this, apart from images, supports ALL types of files, whether multimedia, video, documents, presentations or texts. Supports 15 MB/file and with optional registration to also use it as a personal host (100% free with mail, password) up to 30 MB/file, encrypted. Inclusions script one click for ShareX on Windows or MagicCap on Linux or Mac
The second is vgy.me, also privacy oriented, but supports only images, encryption, 20 MB/image, EXIF Data are removed, API for web pages.
I think it shouldn’t be managed on lemmy side but on the users’ side, e.g. on your device/browser. Libredirect can automatically redirect to those sites, not on just lemmy, but everywhere on the internet: https://libredirect.github.io/
Another problem is these alternative frontends relatively frequently disappear. If you post a link to a random instance, it’s quite possible that 5 years later the instance will be down, and the link won’t work at all. Libredirect addon updates the urls of working instances, so it will work later. There is even a button in the addon to switch to another instance, so you can find the best available site.
