... I had an IT tech from our old MSP tell me her knowledge/recommendation of ABP is what got her the job.

I knew her boss, and doubt that was the reason (probably more because she was cheap entry level labor), but that some people have that take in a professional setting shocked me. I don't think your ad-blocker recommendation will ever be what lands you a job, but I do think it's possible for it to be the reason you don't get a job.
