So can Comodo be any sleazier? Trademarking "Let's Encrypt"?

Comodo has backed down from their, well, cynical and sleazy idea that they were bigger bullies than  a little non-profit, so applied for a trademark for "Let's Encrypt" in October 2015.

In doing that they admitted that they've never used the expression themselves (Techdirt) , and a quick Internet search shows that letsencrypt.org was registered on the web in 2014, and the organization had, as of June 15 2016, issued 5 Million certificates.

When asked about this by Let's Encrypt, there was silence until LE went public, and Comodo finally backed down, abandoning the filing, thankfully, but it begs the question:

Comodo is one of the biggest Certificate authorities, and "The largest issuer of SSL certificates with a 33% market share on 6% of all web domains" (Wikipedia) 

Are they a business that deserves the level of trust required by your security provider?

Oh by the way - Comodo's wikipedia page has a listing about Symantec:
https://en.wikipedia.org/wiki/Comodo_Group#Symantec

Symantec is the company that acquired Bluecoat 

So that's quite the triumvirate - Comodo makes the certs, Symantec now has the client and the SSL-unpacking proxy.

As a matter of fact our computers are definitely not our own
