I recently tried to buy an electric skateboard ($1000+) and couldn’t get to the add to cart button because of the chat interface. A competitor had a similarly rated/speced board so I bought theirs.
That was actually my line of thinking. I was on mobile and it didn’t work. I jumped onto my laptop and still didn’t work. I felt I had put in enough effort at that point. If I didn’t have what I felt was a fairly perfect substitute in the competitors product maybe I would have tried harder.
That requires multiple clicks to 'fix' someone else's website. There should be a more automated (but still suboptimal) solution where you can add Intercom to your ad blocker though.
