There’s a paywall, so I can’t see the “building bridges” part, but the summary says this

In his first interview with Israeli media, left-wing streamer Hasan Piker tells Haaretz that October 7 must be seen in the context of the Israeli occupation, that even liberal Zionists should be ‘named and shamed,’ and explains why most Americans just don’t like Israel anymore

So I kind of doubt “building bridges” was some centrist take. It was more likely about educating ignorant/confused American Zionists out of that mindset, if I had to guess based on what I know of him. If you have access to the article though, I’m happy to read a copy/paste of it.

I do agree that an “Israeli leftist” publication seems suspicious at best. However, Piker appears on other right-wing media all the time. Fox News, Peirs Morgan, etc. So I don’t think his giving an interview necessarily endorses them.
