The issue is not that Glassdoor is being sued, the issue is that there is a company who wants to obtain the identities of those using Glassdoor to make comments about the company. Most people use Blockchain through established services such as Coinbase -- Coinbase, and most other legitimate services like this must comply with KYC rules. So instead of suing "a blockchain", they'd demand the identity of the wallet holder from Coinbase. I can't see how going to a blockchain resolves any of these issues, but perhaps you could elaborate?
