"This is tremendously exciting news for our employees, our customers, our community members, and for our shareholders"
I am a community member: I was not asked for my opinion.
I don't believe that this is really up to you. The site and its content won't actually change (nor will things like the community managers). Nothing should change for you or me, so I don't think it's worth arguing about it. It's just a statement. It is not saying that every member of Stack Exchange is suddenly worshiping the new management, it is simply saying that the majority of us are OK with this new change (and excited for the future). What's done is done - life's not fair.
I would also like to refer to Shog9's answer on the recent and relevant question What does the recent sale of Stack Exchange mean for the community? :
Stack Overflow is all grown up ... Its adolescent innocence is gone, and what happens now must happen with intent and purpose. We'll have to see what that ultimately means...
Overall, in my opinion, this isn't something that we can control.
Can the new Stack Exchange confirm that the existing company will be monetized so that it is worth me investing in it?
This is a multi-billion dollar purchase you're talking about. I don't think SE is going anywhere soon, and if does, then you can raise the issue on Meta.
