Any video surveillance not controlled by you and you only seems like a bad idea. iRobots products have had privacy problems for years, regardless of whether they’re owned by Amazon or not (which they aren’t, merger got cancelled). Alexa does cost them money, but I wouldn’t use any non-FOSS non-self-hosted smart home system for privacy and security reasons.
That’s bullshit, I’m good friends with several ex-partners. Might not work for some people, but definitely not a general rule.
