Subscriptions Block: Inconsistent placeholder text for subscribe button in wpcom between editor and front end

[andrewserong]

In wpcom, the placeholder text for the submit button in the Subscriptions block is rendered as Subscribe in the editor, however we override the defaults for the rendering of the block to use Follow if the block is rendered in a wpcom environment. This makes for a small but slightly confusing difference between the editor and the front end.

The subscribe button is set to use the word Follow in its default placeholder text in this line:

jetpack/projects/plugins/jetpack/modules/subscriptions/views.php

Line 658 in e13487d

$defaults['subscribe_button'] = __( 'Follow' );

Shall we update this to use the word Subscribe instead so that it matches?

Steps to reproduce the issue

1. In a dotcom simple site go to add a Subscriptions block (or select a design from /new that includes the block, such as Bowen)
2. In the editor see that the default placeholder text for the submit button is Subscribe
3. Publish or preview the post and you should see that the submit button says Follow

What I expected

Consistency between the editor view and the front end view. In this case as reported by @p-jackson I expected to see Subscribe instead of follow.

What happened instead

The button rendered with Follow as the placeholder text.
