The only way Google "needs" to collude with corporate MITM tools is its desire to court user base from corporate IT depts (allowed de jure in many countries that have weak privacy legislation).
Usually Chrome is eager to show security-related notifications but for this there isn't even a yellow notification bar with "OK, got it" option.
I think this is another example of how Google clearly puts its own interests ahead of its users.
Google wants to further promote it's closed Chrome ecosystem, and to do that it needs to gain corporate support, for among other things, its Chromebooks and ChromeOS platform.
And it's obviously more important to appease corporate IT than to protect users security.
Built in Google-spying and now, support for corporate spying too? I wouldn't trust a Chromebook as far as I can throw it.
