Yes, it is. Particularly in view of abandoned accounts and folks that have lost keys. I hear about this frequently enough that there is probably a significant amount of Steem unavailable to vote for witnesses. That magnifies Tron's influence some.

Prior to the Soft Fork, I was told Tron controlled 150% of stake available to vote for witnesses. That has since changed, and many more people are now voting for witnesses than were in the past. According to https://steemd.com/witnesses, there was a lot less lost Steem than I had assumed.

Thanks!
