Update heading position on why-fleet.md (#14884)

I moved the "What's it for?" heading. After seeing it on the site
(rather than Markdown) I feel that placing it between the new paragraphs
disrupts the message.

I also addressed some grammar and formatting issues. Removed some
redundant words and rephrased a couple of sentences to give a more
personable tone.

 # Why Fleet
 
-In an industry that views security and IT as a shopping spree rather than a process, it’s little wonder that IT and security teams get stuck with bolt-on solutions, misconfigured tools, and disparate workflows.

 Fleet helps organizations like Fastly and Gusto reimagine the "easy button." 
 
 By simplifying how they do device health, FIM, HIDS, posture assessment, malware detection, vulnerability management, MDM, and the rest, Fleet's API enables teams with thousands of computers to build an IT and security program that works.

 ## Lighter than air
 Fleet is lightweight and modular.  You can use it for security without using it for MDM, and vice versa.  You can turn off features you are not using.
 
-#### Openness
+### Open by design
 Fleet is dedicated to flexibility, accessibility, and clarity.  We think [everyone can contribute](https://fleetdm.com/handbook/company#openness) and that tools should be as easy as possible for everyone to understand.
 
-#### Good neighbors
-Fleet has no ambition to replace all of your other tools.  (Though it might replace some, if you want it to.)  Ready-to-use, enterprise-friendly [integrations](https://fleetdm.com/integrations) exist for Snowflake, Splunk, GitHub Actions, Vanta, Elastic Jira, Zendesk, and more.

 Fleet plays well with Munki, Chef, Puppet, and Ansible, as well as with security tools like Crowdstrike and SentinelOne.  For example, you can use the free version of Fleet to quickly report on what hosts are _actually_ running your EDR agent.
 
-While most folks prefer to use one or the other, Fleet can also coexist peacefully with Rapid7 and other agent-based vulnerability scanners.  This can be useful during migrations.
