Idunno, the web browser has been discontinued for 3 years now. It also seems that bolt.co and Instagram's Bolt are much more similar to each other (apps dedicated to person→person communication) than Bolt the browser is to either of them, so the risk of confusion is much smaller.
My point was that the two Bolts barely compete with each other. One is for voice calls, the other is for quick picture sharing. I can't imagine many scenarios where you could use them interchangeably.
