The article is in response to a very one-sided government ban (well, reported ban) on TP-Link products. The company is being targeted for what appears to be political reasons, the article even said so in the first paragraph:

Experts say while the proposed ban may have more to do with TP-Link’s ties to China than any specific technical threats

It's a very lukewarm response TBH. I would expect a more authoritative opinion instead of rehashing what "experts say".

YOU are the security expert Brian, so stop writing like CNN Tech.

> Shouldn't there be a comparison with TP-Link and all other brands available in-terms of security?

No. Regards, Cisco
