I honestly don't think it's that simple.
While decisions should always be public, in order to come to reasonable compromises on issues, it can be valuable for leaders to be able to have closed-door conversations outside of the spotlight, where they don't have to engage in political grandstanding; after all, it's that kind of compromise that allows democratic systems to function.
In fact, I would make the claim that at least one reason why the US democratic system has become so utterly paralyzed by polarization is because so much of political debate is now happening in the spotlight of social media, instead of behind closed doors where politicians can have the more nuanced conversations that might displease an electorate that is too busy cheering for their team to worry about actually getting anything done.
That's not to say this isn't without peril. Behind closed doors, corruption might happen as easily as compromise. I'm just not convinced the risks outweighs the benefits.
