Paddy Cosgrave, the Irish founder of the Web Summit, drew criticism for a post on social media that was related to Israel’s assault on the Gaza Strip in retaliation for the Palestinian group Hamas’ attack on Oct 7, saying “war crimes are war crimes even when committed by allies”.

Several leading tech companies, namely Google, Meta, and Siemens, as well as various speakers, said that they would not attend the event in response to Cosgrave’s post.

Cosgrave resigned as CEO last month, saying his personal comments on the conflict had become a distraction from the Web Summit 2023 in Lisbon. Web Summit appointed former Wikimedia Foundation CEO Katherine Maher as its new chief.

“I think it’s important to say that I believe everyone, everywhere, has the right to express their views on what is happening in the world,” Maher said as she addressed Cosgrave’s resignation at the event’s opening.

“But having a right to expression, and considering the weight of your words are two different things,” she said.

Most of the attendees who spoke to Reuters said the controversy would not have an impact on their experience and praised the new CEO for addressing the issue straight on.

“They were very transparent…that helps,” said Ellanoor Rep, a 34-year-old tech worker from the Netherlands.

The Web Summit said more than 300 of its partners were coming to the event and that some “who were deliberating have come back on board and reversed their decision”.

A record-breaking 2,600 start-ups and more than 900 investors were expected to attend.

“(The controversy) is a little strange but I think the impact is minimal because…we just want to enjoy the event,” said Spanish attendee Gonzalo Calvo, 23.

The event attracts about 70,000 participants every year, drawing speakers from global tech companies and start-ups, as well as politicians. Some of this year’s high-level speakers include former US army analyst and WikiLeaks source Chelsea Manning and Alibaba.com president Kuo Zhang.
