Making a profit is the nature of business. Requiring payment in giving up privacy and control over your perception as the only options is not, and being a monopoly also is not.
"They all failed or will fail since the point of the 'party' is having everybody attend and attend all at once."
That is exactly why facebook must be faught, the name economics has for this is "network externality"[1] - the monopolization of a dominant communication system by one entity has a cost for those who don't participate, which is not acceptable.
Also, you might want to consider that "having everybody attend and attend all at once" technically does not require a monopoly. The telephone network, for example, is also one telephone network where every participant can call every other participant, but still, there are multiple telcos offering access to the network, competing with one another. Something similar is true for most traditional internet services, and the internet itself. Every machine on the internet can send packets to every other machine on the internet, but there are plenty of providers to choose from. You can send email from every email account to every other, but there are plenty of email providers, and it's relatively easy to open your own. Every website hosted anywhere can be read by anyone, not matter which provider they connect through ... all of those technologies allow you access through one single telephone, email client, and web browser, but there is no single entity that controls all of it, and that is vital in order to avoid an unhealthy concentration of power that in the end is likely to affect not just those who choose to use facebook, but all of society.
