Thank you Justin!

Those are both good points of clarification, and I can update my article to handle those topics better.

For the first one, you're right. I should update the article to say that it works out of the box for browsers that support ES2017. But if you want this to work on an older browser like IE11, then you'll need to transpile the code using Babel. Does that sound more reasonable to you?

For the second point, you are also right. That's my mistake. I had conflated the BSD-Clause-3 license with the BSD+Patents license that Facebook used. Let me review the BSD-Clause-3 license for a bit and then I can make an update.

Thanks for all the great work you and your team have done with LitElement!

I'm curious if you have any drawbacks or downsides you feel like apply to LitElement compared to some of these other web component solutions?
