The Maidan government is not very popular overall though, but mainly because of the co-opting of the Ukrainian oligarchs and perceived weakness against Putin (and Yulia being the inevitable candidate...again). In other words, it's actually disliked more due to the return of the unpopular Yushchenko elites, not because of the 'neo-Nazi Banderist Svoboda takeover'. Most seem to have sided with the Maidan government for now though, due to the ‘rally around the flag’ effect.
Svoboda seems to be viewed as a small, loud and troublesome faction massively played up by the Russians.
And yes, there is a significant minority (maybe 10-30%) of Russian-speakers in Eastern Ukraine that actually do want Russia to annex the East, but it's clearly a minority and even they are rather ambivalent with the Russian infiltrators and their paid crowds.
The only ones who are not viewing Putin as the aggressor over there are the Russian trolls who admit to coming from there to 'give their side of the story'.

IMHO, as I have said many times, Obama and the minions, in an attempt to make Russia “pay” for stopping the Syria attack, have unintentionally created conditions that Putin, Machiavellian that he is, couldn’t possibly pass up.
Events in Ukraine didn’t happen in a vacuum, and Russian Intelligence isn’t stupid. They saw what was coming and made contingencies for it.
