You are indeed correct. I did edit the wrong one.
Here are edits applied on your latest.
collection of software components that runs on an underlying
hardware layer, and that provides a set of software services to
applications which allows them to be isolated from the underlying
software or hardware layer.
* Note 1: For our purposes, it is those software
provided to applications for the creation or
manipulation of user
interfaces and user input - that impact accessibility -
of concern for whether something is a platform or not. An
application offering a compute service, such as a 3d rendering
engine where a requesting application isn't using the software
components/services to create a user interface and interact with
the user, should not be considered a "platform".
* Note 2: If applications typically connect directly to the
underlying layer, rather than relying solely on the platform
software components and services, then it is likely that the
software components in the middle are not acting as a
For example, a program which hosts plug-in's is not a
the plug-in can directly access the underlying layer.
* Note 3: A particular software component may play the role of a
platform in some situations and not in others. Platforms can
include such things as Internet browsers, operating systems,
plug-ins to internet browsers or other software
under some situations, byte-code interpreted virtual
and other "programming within another programming" environments.
