If a company wants somebody to do a hardware audit for marketing purposes, they should pay money for that. Please fairly value people's labor, especially when you seek to profit from it.
Well, influencers are able to work out alternative means of compensation because the content is more valuable than the work performed. For example a blogger that is renowned for teardowns might do the work in exchange for access to early release models so that their content is highly relevant. That is worth more than the hourly cost to perform the teardown work. Compensation negotiation is part of the art of that deal.
If an influencer is indeed able to monetize the content sufficient to match market price for the labor, then sure, that is also fairly valuing people's labor. But that's definitely not what's happening here.
If someone wants to do the hardware audit for free, or in exchange for some kind of promotional exchange, is that a bad thing? I’d breakdown a lot of devices if I could get a duplicate one intact, for free
