I disagree with your opinion, but I respect it.
Everything is interconnected, whether we like it or not, most things today have an impact on others (some more, some less).
I can't say that Eugene Kaspersky will/or is supporting Putin, but it is a complex situation in a country that is not as open as others and at any moment Putin can demand that companies do something for him, and I doubt that if it happened , they would reject it because of the consequences that could occur.
This topic is also not tied only to Eugene Kaspersky but to the product developed by him and his team, if a large portion of users begin to migrate to other products, obviously the level of antivirus protection should fall even minimally, this is one of my concerns.
I like Kaspersky a lot and I confess that it is hard to stop using the product and adapt to others, it is not an easy task
I am still in doubt whether to continue with Kaspersky or migrate to Bitdefender.
