Re: [POLL] Possible scaling compromise: BIP 141 + BIP 102 (Segwit + 2MB)
And how many % are just running SW / core just because of some signed letter politics, hidden or open FED meetings or just uninformed ? What would it look like if all could decide on really a free and uncensored base?
We don`t know. BIP148 anyway need hashing power, or nodes that support it just ban itself from network into no-new-blocks reality 
Indeed. You cannot enforce a soft fork with non-mining nodes. You can just bring them to a standstill.
At that point, the only option for the user is to downgrade to an earlier version of core, or to download a bitcoin protocol compatible piece of software somewhere else.
