Believing that Russua ever favored Trump is the conspiracy theory that no one thinks is true. There is no one Left or Right who don't believe they did try to stick their thumbs on the scale, but everyone also knows their best interest always rested with Hillary.
Personally witnessed true story: between 2012 and 2017 I had a lot of business negotiations with Russians because they were interest in doing a potentially really big project based on one of our products (it ended in nothing after a lot of wasted money... I started out having nothing against Russians in general, even finding them mildly sympathetic, and I ended with a strong distrust and dislike of any self-styled Russian businessman or politician, but that's another story).
Anyway, I had a lot of dealings, included drunken dealings (because sometimes stereotypes are that for a reason) with some quite top tier Russians (and ex-soviet republics) politicians and businessmen.
All the Russians I talked with talked a lot when drinking, and loved to boast and express their very unsubtle political opinions. During these one-sided discussions, it was quite evident that all of them hated with a fiery hate both Obama and Hillary.
On the contrary, they were all absolutely delighted by the idea of Trump getting elected.
At some point, it came out the news that one Russian billionaire living in the US that they dealt with had edged his bets by donating to Hillary campaign too in addition to Trump campaign, and they were all gleefully commenting how this would have trashed his political support back in Moscow (they were happy because now that guy would have needed them to get back in good graces at home).
Oh, even if they loved to imply how they were controlling or influencing this or that, I don't believe the ones I was in contact with really knew or were involved in any way in such maneuvers, and if they had been they would not have talked for sure with me about that. One thing I learned about that kind of people is how much they love to brag and outright lie.
But their feelings? Those were very very clear: Obama was the devil, Hillary was the arch-devil, and once they knew Trump had won they were in heaven.
