If I were giving you €50/month, and then one day I decided to give you USD$55 instead, am I “forcing” you to accept US currency?
Yes, you are literally forcing me to accept your dollarinos, which, unless I exchange them MYSELF, are USELESS!
You provided me, until an arbitrary cutoff day, always the negotiated currency (deb package) but then you, out of the blue, decide to change it to your currency (snap package).
If Canonical want to do their own package, why don´t they just make a new branch and ditch Debian all together? I am not aware of ANY downstream distribution to ditch their upstream's package format, except Ubuntu. Well and those that lie underneath Ubuntu and ditch snap for the super upstream's (debian) package format.
You can always reject my offer. You can ask someone else to give you €50/month.
so either suck it up to Canonical, or go to another distribution provider? Thats your solution to your not perceived enforcement of snap?
