Yes, pinging public DNS servers is bad.
Wrong. It is not bad, at least not so bad, pinging properly anycast DNS servers. The point of anycast is resistance to DDoS. But, relying on hard coded 8.8.8.8 is not a good idea because DNS service of the address may be terminated. Instead, properly anycast root name servers are authoritative resources provided for public DNS queries which can be used for pinging, though pinging so with ICMP should be less painful for the servers.
