I mean, your general gist isn't wrong, but the details are not quite what you're suggesting.
Door to Door sales is a major, major commercial business segment. Most companies use 3rd party door to door sales companies, who employ their own folks to go out and knock on doors and sell things. It can really boost sales numbers, so people/companies are addicted to those sales #s, but they're often highly fucking shady. In Energy, and Telecom, think about people who prey on old folks and get them to sign shit they don't understand. Or fake their signature. Etc. It often comes with a high level of regulator risk, so some companies won't employ Door to Door sale anymore.
Elon basically hired a bunch of pros to do the door knocking. The only thing pros care about is fucking quotas. How many doors did you knock? How many sales did you make? It's a metrics game. And since they're usually third party working on temporary contracts, they're happy to fudge the fucking numbers to make their quotas/get their bonsues considering in a few weeks they'll be working on another contract somewhere else and there isn't much blowback.
Contrast that mentality with people who are volunteering, or have more permanent type positions with a democratic party...people who actually care about the outreach and not just checking a box and getting paid. Or the Culinary Union in Nevada. These people care about actual results.
