Access to the Energy Star reviews requires a 'subscription' too, in the form of a tax. The difference is that people who aren't in the market and don't want to buy it are forced to, for which there is no moral basis.
If there are products that don't have reviews at all, just don't buy them in favor of those that do. In markets where consumers are choosy (e.g. films) companies often ensure reviewers have early access to products to ensure reviews are plentiful.
