Thing is that people with problems are often more vocal than those who don't, especially with service provision. People don't generally come to forums like this because everything is going swimmingly but because they have a problem and want to see if it's them or more general.
And unlike reviewing "things" it's also rare to have as good comparison and what is measured is "intangible". If you compare a "thing" you can look at specification and does it match, it is often measurable (size, power, colour etc). But service is less definable and with more variables; is the slow internet due to the service, others using the service at the same time, or the fact that you are using a 15 year on laptop with 512kB RAM and a really odd wifi dongle that wobbles a bit and is only rated at 5Mb anyway and so on...
