The author is sweet, his conclusion was "always backup your data" if it was me I would probably say "I'm moving away, will never trust them again on my data" ..
Is there a provider that credibly offers high availability Linux servers? Disks fail, capacitors fail, power fails, network equipment fails (a lot). I'm sure it's possible to build an ultra-reliable server that mitigates all that but I doubt it would be worth the money.
At 5$/month, I think it's not too much an investment to have some basic redundancy if you care about your data. Anyways, if your data matters to you, do backups.
