Clem doesn't mention CP-67/CMS, which IBM kept trying to kill in favor of CMS.
From Melinda Varian's amazing history of VM, I gleaned these factoids:
CP-67 - 8 sites by May '68
Feb of 68 - IBM decommits from TSS
Apr 69 - IBM rescinds decommit of TSS
CP-67 - 44 sites by 1970, ~10 internal to IBM
May 71 - TSS finally decommitted
So TSS was a rocky road, while CP&VM were simple and just worked.
Ask the Varians! Lee was a TSS heavy-hitter, and Melinda was...well, Melinda; "What
Mother Never Told You" is still the best document about system maintenance ever
written.
At least as of last year they were both still alive and well.
