Not just companies, but individuals who rely on advertising on their blogs or on youtube. As much as ads annoy me, they also allow for people to generate a small to reasonable income (assuming a really popular blog/youtube channel) and thus continue doing what they love. Maybe they're the minority, but I've heard more than once the past few weeks people complaining about adblocking killing what little income they were getting off their popular online presence.
Also many websites rely on ad-revenue to keep doing what they're doing. The 'companies' will feel the impact of this a lot less than many of those sites you enjoy on a regular basis.
lets make an example of me
I have mixed emotions, I love and use adblock but it does hurt my site obviously
