Pop ups

Not new to Norton used it for years ,can anyone tell why since renewing my subscription i keep getting pops ups asking me to BUY more cover as what i have is not protecting my computer from scary sounding attacks. Does this mean that norton is no better than free protection i can download and the constant pops asking for more subscription to cover my computer is proof of this 

pops saying protect yourself from trackers/the dark web and attacks are the very reason i opted for norton only to find out you are not protected is this the case or is norton using scare tactics to get more money
