Umbra keeping sentience could be related to the events surrounding his creation, whereas others may have been completely willing volunteers that don't have quite so much personal rage and grief to keep them active outside a Tenno's influence. Or him being a Dax. Or improved Transference bolts used later on for whatever reason (depending when they were improved, pre- or post-Tenno, and whether they were set loose on enemy forces or piloted by Orokin). There's a number of possible differences between Umbra and other frames, any (or all) of which could explain Umbra's activity without overturning the Warframe creation methodology.

Also, the thing about current, non-prime Warframes being knockoffs is that it's evident we can rebuild at least one Warframe with whatever consciousness they had before. So, even if they are knockoffs or imperfect versions of the originals, its very possible they're just as alive and conscious—especially if primes are built the same way as Umbra yet display the same inactivity as normal frames. Makes the Second Dream sequence make sense regardless of which frame you use, too.
