"PC or computers or hardware that uses OS that consume FreeBSD, has a faulty software for the router's firmware?"
"The router's software performs ad distributions?"
"The version of internet, the router uses, is updated, whereas, the target machine, or the user's machine is still running a old version"
"The security patch works for the modern but not the precursor version?"
"This leaves older systems obsolete in the market?"
"is this a step-by-step instructions to business owners to introduce new products, selling that older products are obsolete" ?
