I've been running core for years on mainchain and testnet.

I just upgraded from 18 to 0.19.1. I noticed my inbound connections were far lower than normal. Usually was in the hundreds and was just in the 10-20 range after 15 minutes back up, and I noticed an inordinate number of peers connecting and going immediately away.
I never really minded it before,  I did had to set my firewall's bandwidth manager to make that traffic low priority because it would use alot of my upload bandwidth and cause other things I really need to be slow, which worked just fine for years, that's what the bandwidth manger feature in my firewall is for, let it use it when nothing else wants to, when something important comes along, choke off the bitcoin node traffic. Worked fine for years.

So I read NODE_BLOOM is off by default now which is why my connection counts are down. I'm fairly technical generally but not really up on the super technical details of bitcoin clients. From reading the release notes the developers kinda make out NODE_BLOOM as evil. Apparently this was accounting for a large percentage of my node's traffic, so are these evil? Are these just other peers taking more than their giving? Should I turn it back on? I turned it back on for testnet. What's the general consensus on nodes who allow or don't allow NODE_BLOOM?
