This is a most excellent place for technology news and articles.
I use video projectors. Many of them, typically the better ones do not have any built-in smarts requiring an Internet connection.
In general, smart devices are a major security risk, and need to be firewalled off.
There really needs to be laws requiring any smart device to have, like, 20 years of security patches, customer support and liability if anything goes wrong. If they want to place a device, that they insist needs internet access, in my home, they need to, at the very least, pay their way.
