There is still a heavy Russian presence in the Ukraine, especially in the Eastern half.
I’m personally familiar with a Ukrainian family who used to earn money participating in protests like that earlier.
They don’t have any affiliation to either Russia and EU, their criteria of competent central government is the one able to secure monetary aid from both West and Russia.
Pro-Western rallies are a good business for village folks, including people leaning to Russia.
They are getting some $25 a day and a free ride to Kiev - a shopping opportunity in the first place.
