I only have friends on my account, but I did follow what was clearly a "corporate" or entrepreneurial account once, and I simply can't imagine why anyone does it. It's not even virtue signalling, because no one else sees my feed, so the only benefit is that I gave this specific advertiser the unhampered use of my eyeballs. They may not be selling a specific company, but they're definitely advertisers. No thanks.

I could never see why people thought IG or Twitter were so bad until that day, and I'm almost certain it's because they've followed a few corporate accounts and now all their friends are drowned out in the noise.
