Incentives. I use consumerlab because trust is their product, if they break their trust once - they will ruin their business.

I inclined to trust the business which earns money from me - this means they are aligned with value I get and there is little incentive to break the trust and a high stakes to keep the trust when you get paid to be trustworthy.

I trust more the greedy capitalists than politicians in this question because I don't understand incentives of the latter. At least the business model is fairly transparent - you can check the company and how it makes money, in reverse incentives of the governments and their officials is broken - to get elected, get rich, get power, not lose job and keep producing new laws and regulations because if you want to keep your job you can't say “Everything is working, the best thing I can do right now is to monitor the system, collect the data and do nothing for a few years”.
