I would disagree that the article is clear on support for hybrid . The theme of the nexthop article is very much focused on disabling TLS 1.0/1.1 for the purposes of security and PCI compliance. I'm aware that O365 is already enabled for TLS 1.2, the issues is getting on prem infrastructure ready for TLS 1.2. The below KB article clearly states that TLS 1.2 has to be enabled and TLS 1.0/1.1 can remain enabled. I agree that the next shop states that Lync 2010 is out-of-scope of disabling but what it doesn't state is that Lync Server 2010 won't be supported for TLS 1.2 or Hybrid.
"Using TLS 1.2 with Office 365 does not mean you must have TLS 1.0/1.1 disabled in your environments by October 31, 2018. If parts of your environment require the use of TLS 1.0 and 1.1 on or after October 31, 2018, you can leave the older protocol versions enabled. However, TLS 1.2 will have to be enabled and used for communication with Office 365 to avoid any interruption in service."
