Salesforce has over 150,000 companies using it's platform, with estimates around 150 million users... The percentage that use OpenCTI powered by five 9, ctm, gensys, twilio, telnyx, etc... that are WebRTC based if even let's say 10%... that is still like 15 million users daily... not exactly niche for Firefox to be breaking a feature for that many users? Oh and consider that salesforce method for embedding a phone is fairly common, then you have other CRM's zoho, hubspot and customer service platform zendesk etc... all broken with firefox's position on WebRTC...
I'm with the other responder, it is not clear at all to me what you even desire here. I'd say the first step would be to concisely and clearly formulate a way to explain what you are complaining about.
