I think some of your concerns are overstated.
Freedom of speech is a qualified right in the US and probably in most liberal countries. It's true that the qualification isn't explicitly liberal, but it is within a framework that is largely liberal, and by that I mean freedom of speech is protected extensively.
Your concerns about collective power and algorithmic control will turn out to be true If you ignore successful lawsuits against companies like Facebook as well as lawsuits initiated by the United States government for anti-trust violations.
Regarding gene appropriation, have you heard of the case of Myriad Genetics vs. Association for Molecular Pathology?
I would say these can be seen as cases involving rectification of rights infringements, which is a core liberal value.
A primary problem for liberalism, however, has been its historical failure, including the failure perpetuated by Roe v. Wade in recent history, to recognize righthood as such. That is, the rights of all people including the unborn.
But as has already been stated, this is an internal criticism of liberalism according to a freedom that it has itself failed to live up to, not an external criticism involving a failure to define freedom in different terms.
I want to note that liberalism is, to my understanding, entirely compatible with aristocratic or monarchial structures, but I think you are right that it is anti-autocratic.
Lastly, as Banno and Vera Mont have both already acknowledged, critiques alone won't suffice; if you want to change minds, you have to have a recommendation of how to update, modify, or revise the liberal paradigm.
