I flew the coup on OneDrive when they reneged on their promise to provide unlimited storage. They still charged me $50 for the months that I signed up on the basis of that false promise.
Meanwhile Google has been offering their users 15GB and additional storage bonuses for completing tasks such as your annual security checkup.
They did this - to users who had bought Windows Phones advertised with 15 GB (plus 15 GB which were being given to everybody in 2015, total 30 GB).
Kicked back to 5 GB as of Jan. 2016. Except those who knew to ask by Dec. 2015 to an email circulated in forums (as a concession to protests). Those kept their quota.
Asking about lost quota later to MS support was unfruitful - the techs were ashamed but had their orders to not budge an inch.
(Personally saw both outcomes - keeping and losing, for different users - directly.)
