Internet Of Things gets a security patch?

I did not expect that:

In a shocking development, smart lock manufacturer August has been caught promptly patching security holes discovered in its product. 

At this year's DEF CON, security researcher Anthony Rose gave a presentation where he outlined how a whole range of "smart locks" were hackable. 

... 

But what was surprising was that just 10 days later, August had put out patches that fix the holes. Even Rose was surprised, tweeting: "August just patched their web services to stop guest from being able to insert backdoor keys in homekit locks! Kudos to their engineers."

Kudos indeed.  Now if we could just get the other 11 manufacturers named by Mr. Rose to act likewise, we'll really get somewhere.
