I don’t know what a .webp file is but I don’t like it. They’re like a filthy prank version of the image/gif you’re looking for. They make you jump through all these hoops to find the original versions of the files that you can actually do anything with.
Edit: honestly I assumed it had something to do with Google protecting themselves from image piracy shit
I feel like this answer is somewhat warranted because OP seems to have already made up their mind that it’s bad. They referred to it as a “plague” and “filthy” despite not knowing what it even is. This comes across as a lack of interest in the actual answer and more just using this post as a platform to rant about it (despite knowing nothing about it).
It’s not unreasonable to ask everyone here to word their questions politely (or at least neutrally). This is somewhat aggressive, so I think an equally aggressive answer is perfectly suitable.
