The use of OpenDNS is considered questionable by some due to several key 
concerns:

Privacy Issues: OpenDNS, now owned by Cisco, logs all DNS requests made 
through its servers. This means they can see and potentially store 
information about every website you visit, raising significant privacy 
concerns. Since 2015, this data has been under Cisco’s control, which 
may share or use it for various purposes, including commercial or 
security-related activities.

Data Redirection and Capture: OpenDNS has been criticized for 
redirecting Google search queries through its own servers, capturing 
search data before forwarding it to Google. This practice allows them to 
collect and potentially monetize user search behaviorcyberciti.biz.

Censorship and Filtering: OpenDNS offers content filtering, which can be 
useful for parental controls or enterprise security, but it also means 
they have the ability to block or redirect access to certain websites. 
This level of control can be seen as a form of censorship, especially if 
users are not fully aware or in agreement with the filtering policies.

HTH, Jörg
