In many countries citizens have access to all sorts of data from statistics to public spending ( In governments ) that is completly open for anyone to view but here in the UK we don't really have that why not? I know we do have if FOI but making a FOI reqest doesn't guarantee you will get an answer nor is it the same.
Any data that does not contain sensative/personal information could be public as there is no need for it to be hidden. I know this does add extra resouce costs when doing this but by doing this people will have more trust.
Talktalk could do their part by listing data per year
1) How many new customers signed up to talktalk
2) How many are long term customers ( IE. 5+ years )
3) How many have ended services or switched to other providers
4) Total number of customers by the services they have ( IE. How many have TV/Mobile with broadband and phone )
5) How many customers have had few or no services ( Due to outages )
6) Average length of times outages lasted ( IE. in days/weeks/months )
7) How many customers receive close to expected speeds ( For the package they have )
😎 How many customers receive poor speeds ( For the package they have )
They are just a few that i can think of right now but other people may have their own ideas, I would like if someone from talktalk could respond to me too on this matter.
