You are confusing your own products. AdSense. Not AdWords.
The various forms Google makes available for appealing suspensions are pretty much useless.
I urge you not to believe what I am saying here as well as not feeding within your own internal echo chamber. Use your own search product to search the 'net for the thousands of stories of various forms of algorithmic account suspensions, the damage they cause and how frustrating it is to get anywhere with Google.
Based on what I've witnessed personally and what I've read online the idea of relying on Google products for anything business critical terrifies me.
You --Google-- needs to truly care for it's clients and, as I said in a prior post, issue a guarantee. I am NOT talking about a guarantee of uptime for a service, that's irrelevant here.
What I am referring to are guarantees of service longevity as well as protection and recourse from algorithmic account suspensions. A business person needs to have the ability to address and discuss misunderstandings or problems and not have their entire Google-provided infrastructure evaporate overnight with nowhere to go.
To me the matter of free vs. paid is immaterial. Google and companies like Google use free services to gather and monetize audiences. For example, nobody would pay for search. Nobody would pay for a Facebook account. So you use free to bait the hook and capture audiences. This is a technique as old as the Internet, with browsers such as Netscape and earlier being the first land-grab-through-free-products.
If you are going to have a virtual monopoly by resorting to free products you also have to have the responsibility of not causing your user base irreparable damage by pulling those product either by early termination of the services or termination or suspension of account without recourse. At the moment you are large enough to not have to care about this one bit and nobody has challenged you in court for this terrible issue.
