“Why not just make the 4 titles the same book?”

 Because they were aping the success of Superman and Batman who also had multiple interlocked titles to their name and also, if one bothers to check out the other titles released alongside Sensational #0 you’d notice that the 4 titles were gradually getting less and less interlocked as time went by.

 “The cover is BORING!”

 It’s giving you a clear shot of the new outfit whilst not involving other distracting elements in order to highlight the costume and make it impactful. It’s called minimalism.

 “What’s known as the Sensational costume”

 Nobody has ever called it that, it’s either called Spider-Girl’s costume or Spider-Ben’s costume.

 “Being Spider-Man has only ever resulted in good right <sarcasm>”

 Well...yeah it has. He’s saved countless lives and his mere presence as a crime fighter reduces the crime rate. It’s been shown people suffer when he isn’t out there being a hero.

 “Why didn’t you just use actual lockpicks?”

 Because maybe he doesn’t know how to pick locks and doesn’t need to carry around that equiptment when he has his robots with multiple functions to handle that for him?

 “Stick to simple stuff before you’re sure you have more resources”

 In an emergency Spider-Man may well need to expend a similar quantity of web-fluid in order to create web nets to catch himself, civilians or debris during battle. His web-shield (seen in the image) can also protect him from damage including bullets so testing the webbing can handle that stuff is vital.

 Moreover web-fluid doesn’t run out THAT fast. Making like three web shields doesn’t actually deplete too much from his over all supply.

 “The Daily Grind’s name is stupid because it reminds college kinds of the stress and lack of funds they endure”

 I’m pretty sure that the name was intentionally ironic.

 “Desiree is a douchebag”

 When she asks Ben to move tables sure. Just walking in though she’s just having some fun. Gwen and MJ weren’t that different back in the 1960s Spider-Man comics.

 “Armada’s helmet is goofy because of the wings on it!”

 Doesn’t Captain America and Thor’s costumes also involve headgear with wings on them?

 “Blonde people ALWAYS have money”

 It is obvious he was referring to his unkempt hair and beard, not the fact that his hair was a different colour

 “The story is repetitive because it bookends the issue with mentioning power and responsibility”
