This is unlikely. I'm pretty sure over at the GitHub issue they state that they didn't even need AdAway installed. Having systemless hosts enabled was enough to cause the issue.
For me, I had about 5-6 freezes in 24 hours since I did a clean wipe and install of 11. Last night I disabled systemless hosts and so far I have had no issue.
Also, the latest version is 4.3.6:

So - honestly, I can't believe a word of that post.

Don't doubt your experience, but I've had the issue since I did a 100% wipe and install of image (not just a factory reset). So far, after 24 hours of freezes, I disabled systemless hosts and since 11pm last night I haven't seen an issue.
I can't conclusively say that systemless hosts is what has done it to me either. I am going to run without it for the rest of the day, and enable it again tonight and see if I have the issues.
