Ok…
You know you can disable plank
( dock ),
see Budgie Desktop Settings and remove plank from « automatic startup ».
Still it’s not Budgie’s fault if snap
behave rough around the edges sometimes.
You can also disable snap
if you want - official APT/.deb repositories are not meant to disappear : Chromium though unfortunately is only available as a snap in *buntu, so if you need it daily, modify its launcher as suggested above { launchers placed in ~/.local/share/applications
won’t get touched by updates }
All other programs are still available as .deb through official repositories and ppa, newer versions of LibreOffice or Gimp or Minecraft… Snap things are not at all mandatory ( except for Chromium ).
A package manager like synaptic
will show you only APT/.deb related offers.
snap-store
well as its names suggests will only show snap things.
gnome-software
aka software
may show many things, even flatpak if you add the right plugin, so while using it always pay attention to the « source » of app’ and choose wisely.
Wisely means first best choice is .deb from official repositories, second best is .deb from a trusty ppa. If what you need is not there, try something else ( snap, flatpak ). In last alternative, AppImage or compile from sources.
And please for second time : beware here are benevolent volunteers, not paid workers for providing free support to bratty people.
