what’s wrong with mega they offer 50GiB of free storage that you can access from a browser (they have Chrome and Firefox addons for faster access) or a desktop client (they have one for mac win and lin) they also have an android and ios app
the only limits for free accounts is the 50GB of storage and 1 TB of transfer per month so you don’t leech them out of business
and their storage is encrypted so they don’t have access to your data
