It’s kind of a paradox when you think about it. Good reviewers are often just regular people with a passion for tech but as they become more popular and prolific they become part of the industry itself. Once that happens even if they try to stay objective and critical their perspective is so different from regular people that reviews are just part of the sales and marketing strategy rather than pro tips from an enthusiast.
Back in the day people paid for ringtones, wallpapers, etc. Dumbest thing ever were ‘ringbacks’ where you paid to have a song or something play when people called you. So the people buying it didn’t even hear it, they just forced other people to listen to a shitty low fidelity garbled mess of a song they liked while you waited for them to pick up the phone.
