On Tech Tent this week we hear how the Supreme Court is hearing claims that big tech firms such as Google and Twitter should be considered the publishers of the harmful content that appears on their platforms - Dr. Mary Anne Franks, President of the Cyber Civil Rights Initiative, tells us how it could change the way the internet works everywhere in the world. A year on from the Russian invasion of Ukraine we speak to one of the country's thousands of tech workers about how she has adapted to living and working in a time of war - and the government tells us the tech sector has kept growing, despite the destruction and loss of life. We find out about how some internet users in South Africa have had to become night owls because of the soaring cost of mobile data. And how to ride a virtual reality jetski - just by thinking about it.
