[Nut-upsuser] Why are LAN ports not standard on UPSs these days?

A couple of decades before I was retired and was still working for other 
people I had cause to install UPSs and they usually had RS232 ports to 
allow the setting up of shutdown scripts to UNIX / Linux servers.  Now, 
after not having to be concerned by those issues for some time - most of 
my little web sites have been on Digital Ocean or other suppliers VMs 
for a long time - I am shutting down my DO servers and bringing my sites 
in-house.  However, now I need to be concerned about reliable power 
again so I have spent a bit of time looking at options and I don't 
understand why most of the UPS offerings available do not come standard 
with a LAN port?  Why is this?

Do people have suggestions about my options?  I have two main machines - 
say 250-400W total and a few small devices inc a Billion router and some 
USB devices.  It would be nice to have at say 5-10 minutes battery 
backup before sending shutdown messages to the Linux machines.
