We have reported on this case earlier - in short, when Dr Shiva was running for elected office in Nov 2020 he was deplatformed by Twitter. He went to court:
"Following the deplatforming of Dr.SHIVA, testimony and hearings in Federal court elicited how government and Twitter have created an infrastructure for government to launder censorship of speech through Twitter"
The case continues, and those who are interested (if they do this in the States then who would like to bet that they don't do it in the UK?) can follow the case on the case web-site created by Dr Shiva, who is representing himself (I guess he wants the job done properly and to his satisfaction).
Dr Shiva's is a test case to break the illegal (possibly fraudulent) claim that Twitter operates independently of the government (or indeed of any other organisation or political party).
(Those who value freedom of speech might care to make an appropriate donation via the same web-site - the case will have effects wherever Twitter operates.)
