Spike:
He uses Pokes that have been proven to be successful in some manner.
This is actually a better portrayal of a Spike than the previous description. In magic, Spikes AREN'T that creative... they are primarily net deckers that go to tournies to win them. If they change a card in their sideboard it is cause for discussion. Spikes are fairly rigid by nature. They play it safe, and wont make a change they dont know to be better.
A quote:
"Spike is the competitive player. Spike plays to win. Spike enjoys winning. To accomplish this, Spike will play whatever the best deck is. Spike will copy decks off the Internet. Spike will borrow other players’ decks. To Spike, the thrill of
Magic is the adrenalin rush of competition. Spike enjoys the stimulation of outplaying the opponent and the glory of victory." - Mark Rosewater, MTG.com (he helped come up with these profiles and named Timmy and Johnny)

There have since been further classifications of these categories, but the article the OP addresses doesn't mention them.
There is 1 out of the 4 classifications of Spike that even closely resembles a Johnny/ Spike:
"The Innovater:
This group is the closest thing Spike has to Johnny sensibilities. (Although I should point out the Innovator Spike wants to win first and foremost; he doesn't feel any need to be novel or unnecessarily different.) Innovator Spike prides himself on his ability to judge new cards. His goal is to find the next broken thing. Innovator Spike's dream is to spawn the next dominant deck. He wants to break the game. And like Johnny, he wants credit. Because Innovator Spike is so focused on breaking new cards, he spends a great deal of time understanding the nuances of the mechanics. If something broke once, odds are greater that R&D will misjudge the same thing in the future. Because this group wants to understand how the game ticks, they are the ones most likely to be interest in
Magic game theory. They want to understand things like card advantage and card utility because it is this intimate knowledge that's going to reward them later on." -Mark Rosewater, MTG.com

Here is some middle ground. 3 shallow categories are too broad to categorize something as complex as a human style of play/ motivation to play... they had to break them down to make the terms work better. THIS category is really what I have been trying to describe. He admits to doing this here:
"One of the biggest stumbling blocks is that each group had a clear stereotype that pulled focus. That is, when we talked about the psychographic profiles, we had a tendency to err in talking about one particular subset at the expense of the rest of the profile. That, I feel, is what I did in my first article on this topic. I oversimplified to the point where I reduced each profile to a stereotype. This has caused a number of inaccuracies and misunderstandings (one might even call them myths) about each of the profiles. Today, I'd like to set the record straight by doing a better job of clarifying each profile."

This does nothing to change the fact that competitive pokemon is bad for the 3 generic types of players. A Spike by the original definition was rigid, and largely a net decker. However, they have since specilized the categories to make them less clunky and make them fit peoples style of play a lot better.
The innovator and the Johny/ Spike are really only different in that the innovator will always put winning first, even if it means sacrificing creativity. That isn't guaranteed to be the case for the Jonny/Spike who REALLY desires to be innovative to a degree.
CAPEFEATHER:
Largely, you are right about the Spikes. Before they had a name it was Timmy, Johnny, and Tournament Player.
