companies seem to have a wall to prevent customers from submitting or monitoring bug reports
That is actually not really true. I understand that you have some specific companies in mind, but please remember that most open-source projects allow you to do exactly that: get involved in the development, at least by submitting bug reports. Many of the open-source projects are actually backed by (big) companies.
On the other hand there are the companies which don't actually care about the customers. Consider Microsoft: what people actually complain about vs. what actually happens with their products. Reports of problems are very detailed throughout the entire Internet, and yet their products become worse with every generation. Remember the forced restarts and the lost work in the Windows 10, for example?
In the middle you will find the companies which organize a more-or-less good customer support, where any average Joe can complain in his own words about the issue, and then the issue will be translated to technical jargon internally in the company. These companies might be able to give you the chance to provide a technical description, probably by providing you with an e-mail address.
Monitoring the bugs by the customers is another "monster". That is considered by most commercial companies as strategic secret information, and releasing it to the public is considered very dangerous. No offense, it is just business. You would probably do the same, if you would run your own company.
