Because most of the new hydroxide ions are removed, the pH doesn't increase very much.
Removal of the hydroxide ions by reacting with hydrogen ions
Remember that there are some hydrogen ions present from the ionisation of the ethanoic acid.
Hydroxide ions can combine with these to make water. As soon as this happens, the equilibrium tips to replace them. This keeps on happening until most of the hydroxide ions are removed.
