Snap(chat) is Gfycat's parent company. The short version is they're hemorrhaging money and have been for years so they're cutting this as part of cost saving measures.
Yea me too i am a bit wondering why. People kept saying this was the reason, but idk if they really mean that or if its just 'saying what sounds possible as a half joke' (like when people answer any question about any shady business or very expensive auctions as "its money laundering" even tho there may be other explanations. I think ppl say it half jokinly?) Idk what reason snap would do this tho? Maybe theyre planning to make a gif hosting thingy by theirself?
