Anybody knows who make these robots and what model is it? Can i buy this robot?

They’re from a company called Starship but I’m not sure who actually makes them

I like it! Thank you! I think it would be very useful at least for newcomers.

They have bot in telegram @smartvotebot

Web app can be easily blocked by government. Look at telegram in Russia. Native app still useful without vpn.

This doesn't even make sense. Blocking is blocking of network connection. Native apps still need that to talk back home

Native apps can be a bootstrap shim for a more distributed back-end. PWAs are not going to be loading off onion nodes or ephemeral distributed networks any time soon. Native apps, especially those that can side-load or update without the app stores, will always be more resistant to these sorts of attacks.

Telegram uses push notifications to update its server ips.

Are there more books or sites about car hacking except "The Car Hacker’s Handbook"? This is very interesting topic.

Sure.

Yes, it is
