Don't buy things that need a cloud integration and it's not really a risk.
Even if you don't use Home Assistant, their site is really good for helping with this--every integration lists a "class" like "Local Polling" or "Cloud Push".
Another shortcut is picking up a Zwave/Zigbee dongle (~$30 when I got mine) and buying products that work with that. If the only radio in the device is one that can pair to a local controller, it's a relatively easy way to ensure it's meant to work locally without a cloud integration. (If Kwikset has a bad quarter I'll never know--my door lock only communicates as far as my utility room.)
Besides "the company can't screw me over", if everything is running locally it also immediately limits the privacy and security implications. And ensures your house doesn't break if the internet goes out.
