nothing is forever but google drive is free
Archive.org if you are looking for a public place.
If you are looking for private use, I would recommend taking a small/old PC and run Yunohost with Nextcloud.
Also all depend on the stuff you’re talking about…
It depends what you are after.
Even though Google has a long history of killing their products I doubt they’d do it to Google Drive anytime soon. You could upload it there and make it publicly available. Proton Drive is newer and preferred by a lot of people for numerous reasons. It has a 5GB limit. You could probably use that.
I feel like the key is having at least one other place where it is in the event one service dies.
That said there are paid services out there that would likely keep your files indefinitely and are unlikely to shutdown anytime soon.
IPFS maybe
