Office 365 is a subscription, not a perpetual license, but the only time I can recall Microsoft ever deliberately removing access to downloadable software I was entitled to was in the late 90's, when they removed Windows 98 and Windows NT 4.0 from MSDN as part of a settlement with Sun where they agreed to stop distributing their Java runtime. Oh, and just for the record, one time in the early 90s, I was getting read errors trying to reinstall Excel from the original floppies, had no backups, and Microsoft support sent a complete replacement disk set, at no charge, no questions asked (seriously; for all they knew, I could have been lying to get a free unlicensed copy of Excel).
