I work in crypto. I have nearly no stake in Solana or any Solana based project, but I have done a little bit of smart contract programming on Ethereum (actually working on changes to a popular lending protocol that has built-in governance for upgrades)
My personal opinion is that the Governance URL would be far more neutral than any article or thread where people are piling on to use this to criticize Solana (the same change to a protocol could happen, and probably has happened, on Ethereum). The /r/cryptocurrency subreddit is not neutral when it comes to Solana, and 99% of the commenters don't understand what they're talking about.
Criticizing Solend if the proposed changes are made is fair, but this is basically how DAOs work... token holders vote to make proposed changes. If you don't like the existing implementation and governance process, you should avoid the protocol, or pay attention to what might change that could affect you.
If I sign up for a web service and agree to a ToS (which always says it may change and that continued use means I'm agreeing to any future changes), I have far less transparency into what changes might be made. Solend users agreed to the protocol implementation which includes upgrading without a timelock (bad practice). But at least there is a governance process, which gives users a chance to get out when unfavourable changes are happening.
Also, I don't know enough about Solend or Solana to verify this, but users of lending protocols typically get a distribution of the governance token based on their stake, which means the "whale" being discussed likely could block this vote if they wanted to.
