The side completely, 100% opposed to any restrictions on speech (including "policing tone" as outlined in this presentation) will see this as corporate meddling in people's expression.
The side that supports speech regulation will see this as a structured plan to curb the kind of speech that's considered "harmful" or whatnot.
This presentation doesn't contain anything outside the current ideological dichotomy, no original or unorthodox thoughts or ideas.
