I haven't made up my thinking about this yet. I think first there is the principal question. Is a library deleting content always a violation of free speech? And I think the answer to that question is no. A library comes with an expectation of quality, so they must do do content curation, keeping quality content in and low-quality content out. Those who are not judged to meet the bar are not silenced, they have other options for getting their opinions and material out. But the harder question is whether this particular material was unfairly singled out or not. If the library is unfairly suppressing quality research then that would be a bad thing. I think what would help me understand the situation in that respect is if someone posted examples of high quality research that was deleted but arguably shouldn't have been.
