It's not necessarily avahi doing that. A DHCP client might also 
configure a 169.254.*.* address for you if it doesn't receive a reply.

In order to have the slightest chance of helping you it is necessary for 
you to provide the information as per below.

Files should preferably be attached, to avoid issues with copy-paste. 

Please do not edit anything except to obscure private information (e.g. 
passwords or a public IP you don't want to post).

1. content of /etc/network/interfaces and all files under 

(I seem to recall you are using ifupdown)

2. Full output of:
apt list --installed 'network-manager*' # might be empty
apt list --installed 'avahi*' # might be empty
systemctl status systemd-networkd
ip a # short for 'ip address'
ip r # short for 'ip route'

3. Information on anything (and I do mean anything) else you might have 
done to your network configuration after installing buster, including 
but not limited to:
 * installing stuff, especially if from source
 * removing stuff (especially if not 'purged', dpkg -l would tell)
 * manual changes to files (deletions/permissions/etc.
 (especially those unnecessary "fixes" you call "neutering")

For the record/archives: other users are not seeing your problems.

Buster is - at least for me - the best Debian release yet.

The problems you are seeing are, at least partially, of your own doing, 
most likely due to wrong configuration and an approach of using the 
equivalent of a shotgun to kill a fly and then complaining your walls 
are full of holes.

Kind regards,
