The biggest mistake users will make is thinking their data is safe JUST because they have a NAS or a RAID. It’s common parlance in Systems Administration that RAID is NOT backup.
To wit— not truly understanding RAID and how it relates to capacity, parity, and especially the time required to rebuild in failed disk situation. It is a crucial mistake to use RAID 5 with greater than 2TB disks, and even that is pushing it, but RAID 5 is at least in the zeitgeist.
There are also some outside concerns such as Drive batch dates and knowing to pre-purchase spare disks well in advance that may hamper recovery.
You are absolutely correct— major blog hosting, image hosting, and video hosting sites are all “free” for the content creator, but YouTube by far has the largest audience and highest monetization rates of any of them.
This is just creators buying in with their wallets; it makes sense to go where the money is, even if the format sucks for the idealized content consumer.
I wouldn’t immediately jump to that conclusion. There are plenty of legitimate business opportunities that do not imply “taking money to promote products”. In-line advertising and properly disclosed free samples are standard operating procedure for the tech industry, but they are completely above board, and by themselves do not imply bias.
Nearly every content creator’s YouTube channel About page or website will have a similar line, somewhere.
