Yes, JFR must have been popular with some. That quote at the end from Johnson (who is quoting an unnamed individual) indicates that JFR had a likeable side when he wasn't 'being a lawyer', by which I think he really meant 'being a bully using his lawyerly training' (no offense, BotR :-)
I think the area where he most relied on popular support was when he was voted in as the obvious choice for President (even if that didn't indicate affection for him, just respect). The bylaws that gave him greater power were apparently approved by a naive Board, and then he replaced the rebellious Board members with friends, so at that point he no longer needed majority support.
One interesting part from Johnson's testimony (at the time his muscular arm was grabbed by JFR) was that:
At this Bro. Martin started to hoot at me, and was joined in by quite a number of Bro. Rutherford’s sympathizers. So greatly were the feelings of the majority, myself among them, outraged by this exhibition of rowdyism that they left the dining room.
He is saying that the majority was not in favor of JFR at that place and time. However, according to Wikipedia, a referendum of subscribers in 1918 gave JFR 95% of the vote. I think it's safe to say that he who had the Society had the reader's support. The average reader knew nothing of JFR's personality and simply assumed that the Lord was with whomever was already in control (who was elected, after all).
Interesting aside: I see no references to the divine name anywhere in the 1917 publications "Harvest Siftings" et al. It doesn't seem that Bible Students made frequent reference to it back then.
