AFAIK they don't censor, they like the new UI so they don't agree with the upset vocal minority and hence ignore the nonconstructive criticism. Most people don't have problems with the new UI. Like maybe 99% but that's just my guess.

Yeah, that's ignoring. Censoring would be deleting or hiding the thread. People are free to create new issues as well.

Thanks for filing the issue..!

As the issue seems to be similar to that of   Issue 911820 , hence duplicating into it. Please feel free to undupe if not the case.

They are blocking the issue so as to those who are raising voices. For someone to stay relevant and get paid, they'd have to do something new even if they're terrible. As for everyone else they're just enduring in silence what's been forced or they don't care much. They just want to browse something, if browsing work they're happy. 

I'd not have cared much if I didn't use previous design. Everything in the new design just screams I'm there. It's good for a touch device, but for a non-touch device with small screen it's nightmare. Even Firefox looks better now than chrome with it'd prefect rectangle shape instead of weird oval shape like in chrome.

Personally I hated the new UI at first, but then I've customized the theme colors so it no longer irritates me.
I've used this theme editor: https://www.themebeta.com/chrome-theme-creator-online.html

There's a long thread in forum https://productforums.google.com/forum/#!topic/chrome/0KBceiK5iL8

https://bugs.chromium.org/p/chromium/issues/detail?id=913806#c6, I don't think I can use that to go to previous design then why bother changing some colours.

At this point there're 3 choices
1. Use other browser like Firefox
2. Use one a chromium fork without this weird quark -> https://www.centbrowser.com/
3. Use older version(pre 71) of Chrome -> https://www.slimjet.com/chrome/google-chrome-old-version.php
