You are incorrect, it's been made clear that the River Parks, a pubic entity, owns the park and that it is leased to The Gathering Place which is a LLC. owned by River Parks.
"gave ownership to River Parks Authority, which signed a long-term lease back to an entity of the foundation"

"Tulsa’s Gathering Place LLC, a wholly owned subsidiary of the authority. Gathering Place LLC is the legal name given to the Gathering Place park in 2014 when it was given to the River Parks Authority"...

As for funding again it took $65mil. in taxpayer's funds to make it possible.
"The city has spent about $65 million on infrastructure in and around the park, including $15.9 million to reconstruct and upgrade Riverside Drive".

Interesting to not that while considering itself private the gathering place wants water utilities paid by the taxpayers.
"The foundation has also requested that TMUA provide free non-irrigation water and sanitary and storm-water services for the park in perpetuity".

As for ongoing cost if this park agreement is like with the pedestrian bridge routine and nonstructural maintenance is separated from capital improvements which one would think would include certain major repairs which the city is responsible for. The fully explained agreement about what the Gathering Place, River Parks, and the city are responsible for should be made public since a public entity and tax dollars are involved but it hasn't.

It should also be remembered that in 2007 voter refused to fund the idea of a new river park development yet now tax dollars have went to it and may continue without voters having any say.

As for the OP being a douche it how is it that some exercising rights are wrong and others right? Are gun owners to be the new minority that can have their legal rights as long as they don't flaunt them and get "uppity" about them?
As for legal action since an article mentioned that at least one of the people removed belonged to OK2A I'm guessing there's a good chance Don Spencer may well become involved like when he had no gin signs removed from other parks. And that might be good since legal action involving the claim of a "private park" would likely bring clarity about funding and agreements that have been made involving public property and funds which only certain people were involved in.
Hiredhand addressed your public entity comment which was incorrect. The perpetual maintenance and security is taken care of by the trust for the next 99 years or something like that. Which has nothing to do with the bridge. This is all public info.
In terms of being a douche, sorry but he is in my opinion. He should've filed a lawsuit.
